This thing is no joke. I left my shake in my baking hot car during work and it was still cold when I grabbed it after. If you hate warm protein shakes, you NEED this.

Originally bought this for my protein shakes, but now it's my go-to for everything. My wife swears by it for her poolside margaritas (no more watered-down cocktails), and I use it for my cold brew heading to work.

Good product but I need a tad bigger capacity for the cup

I've tried it all: ice cubes, gym water fountains, you name it. Nothing worked when on the go. My shakes were always warm and gross. ICEBRRG is a total lifesaver! Now my shakes stay ice-cold and are never watered-down with ice.

Best Shaker i have owned. Mixes great, stays cold and easy to clean

I used to chug my shake just to get it over with. Now it stays freezing cold and actually tastes good. ICEBRRG is like having a mini fridge in your gym bag — absolute game-changer!

Between work, the gym, and everything else, I needed something simple. Freeze it, mix it, done. My shaker sits in my gym bag all day and it's STILL ice-cold when I'm ready for it.

Just received yesterday I put the ICEBRRG agitator in the freezer over night put some water in the cup and water is cold. Love it recommend you get yourself one.

This shaker is super solid and does exactly what it says, stays cold all day and never any smell from my protein

Very good product
